Type
CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Function
A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.

office / hotel

Structural Material
Steel
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.

Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.

Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.

Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.

Composite
A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.

Height
Please note that this height is estimated, based on a floor count of 120 floors. The estimation has been arrived at by analyzing 324 other buildings of the same office / hotel function on this database that do have confirmed heights. The user should be aware that non-standard features, such as significant spires or raised entrances / podiums, may affect the accuracy of this estimation.
Architectural
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."

525.0 m / 1,722 ft

To Tip
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).
601.0 m / 1,972 ft
Occupied
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
494.4 m / 1,622 ft
Observatory
484.4 m / 1,589 ft
Floors Above Ground
The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).

Floors Below Ground
The number of floors below ground should include all major floors located below the ground floor level.

# of Hotel Rooms
Number of Hotel Rooms refers to the total number of hotel rooms contained within a particular building.

858

# of Elevators
Number of Elevators refers to the total number of elevator cars (not shafts) contained within a particular building (including public, private and freight elevators).

96

Top Elevator Speed
Top Elevator Speed refers to the top speed capable of being achieved by an elevator within a particular building, measured in meters per second.

6 m/s

Tower GFA
Tower GFA refers to the total gross floor area within the tower footprint, not including adjoining podiums, connected buildings or other towers within the development.

About Makkah Royal Clock Tower

At the heart of the holiest Islamic city, Makkah Royal Clock Tower brings an air of modernization to the bustling historic center of Mecca. The tower was developed as a component of the King Abdulaziz Endowment Project and provides comfortable accommodations for devout Muslims that make the journey to the city every year during the Hajj period. It is conveniently located adjacent to the Grand Mosque, which can accommodate up to two million worshippers over the course of the event.

The clock tower stands in the center of a high-rise complex called Abraj Al-Bait. Six smaller high-rises surround it at heights varying and accommodate both residential and hotel uses. True to its name, four colossal clock faces are mounted near the top of the tower. These clocks hold the record for both the largest and highest in the world. At night, the clock faces are illuminated by one million LED lights that transform the tower into a green and white beacon. Writing is inscribed above each clock, with the words “God is the Greatest” on the north and south sides, while the Koran adorns the east and west sides. The spire of the tower features a spherical observation center at its base. The spire is capped with a shining mosaic gold crescent that weighs 35 metric tons. A number of cultural amenities are present in the upper levels of the tower, including a center for lunar observation and a cosmology museum.

Since a great deal of residents and guests in the tower perform prayers five times a day, innovative solutions were provided in the elevator systems that transport people in a smooth and efficient manner. Group control systems were implemented that adapt to the travel patterns of passengers, intelligently anticipating their general location and destination. Using this technology, up to 75,000 people can exit all seven buildings without issue.
